Supported in any suitable manner heti een the chute member 22 and theadjacent casing; of the carding cylinder is rock shaft 23.

For the purpose of illustration the rock shaft 23 is shown supported foroscillation in bearings 24 and eachbearing attached to a suspensionstrap 25, and each strap adjustably coupled to the nearest supportingarm 26 of the flat belt. Each of the hanger straps 25 is slotted toreceive clamp bolts tapped into the arm 26, whereby the bearings 24 maybe adjusted vertically to control the position of the rock shaft 23.

The shaft of the lickerin 14 is supported by brackets 29 rising from theframe 10, and connected to one of the brackets is a relatively heavystrap 30 to the outer end of which another bearing 31 is attached, andjournalled in the latter bearing is a stub shaft carrying a belt pulleyThe shaft also earn s a similar belt pulley and an endless belt operatesover tr belt pulleys. By this means the motion oi the shaft 28 of thelickerin transmitted to the stub shaft 32.

Mounted on the stub s V 32 at the end opposite to the pulley 1s a uishaving an undercut or dovetailed guide channel 37 in its outer face.

Slidably disposed in the channel 3? is a headed stub 38 carrying athreaded sleeve 39 as shown in Fig. 5, the latter Serving the twofoldpurpose of a clamp nut to adjustably couple the stud 38 in the. channel37, but likewise as a bearing for a connecting rod 40. By this simplemeans the throw of the connecting rod may be readily changed by changingthe position of the stud in the channel 37.

At its opposite ends the rod 40 is pivoted at 41 in a slot 42 in an arm43 connected to the shaft 23 and partaking of its rocking motion.

Extending through the shaft 23 at spaced intervals are bolts 44 havingcoactinp; nuts 45 bearing upon opposite sides of the shaft to enable thebolts to be adjusted transversely of the shaft.

Attached to the bolts 44 at one end is the head member 46 of a combblade 47 which operates sufliciently close to the latter to strip thematerial therefrom as the flats are rotated.

Pivoted at 49 upon opposite sides of the casing of the carding cylinderare small levers, one of which is shown at 50, and pivoted at 51 to oneend of the lovers is a guide bar 52, preferably of relatively heavymetal with its upper face curved to conform to the curvature of thepaths of the teeth of the flats 16, and yieldably supported by anysuitable means, for instance by springs, one of which is represented atThe member 52 operates as a guide to the flats as they pass around thedrums so that the flats will be held in position where they pass over"he r-stripping comb for the comb to remove the strip from the llats.The stripping comb Ii-7 must be set to opcrate very accurately, hen-ethe neccs for the guide 52 to cause the flats to travel accu telyrelative to the comb.

ch the ap aratus thus described the oration is as l'ollows:

its the carding cylinder and lickci'in are rotated, tlle lap of cottonincluding the llll purities if any l by ilu roll 48 lo the lickcrin andthence and between the latter and the flat devices. The flats beingrotated opposit ly to tie movement ol. the card cylinder the matci al\Tilliu} the impurnie." will be moved to the outer sumace of ti is ofthe lap and be picked off by the tcet 1 of the flats and carried awayfrom the influence of the teeth of th. cards. and thus separated fromthe major portion of the material. As the picked off mate rial is c-'ricd away from the carding inder the oscillating comb device ilkstripsthe material from the flats and (onducts it into the chute or hopper 2'2and thence into the lickerin.

The stripprd material passing lu-oug'li. the lickcrin, the

150 the carding cylinder .-;er amount oi tlierra.-;li. motes and otherforeign matter exhumed by the action of the lickcrin and by which theyare broken up and ('Xll'lll'itfil by the mote knives represented at 49.

Thus much valuable time and labor is saved as the work in the stripperroom may be entirely obviated.

By this arrangvment the card strippingrs may be reworked simultaneouslywith the carding of the lap material, thus avoiding the necessity fortaking oil the strimiings separately and transporting them to a stripperroom to there be worked orsold as waste In treating certain kinds ofcotton. it is not desirable to run the strippings through the lickerin,and in that event a stripping roller. represented at 54 in Fig. 12, issup ported on the funnel 22 in )0sition to carry the strippings over thefunnel and deposit it in a suitable receptacle or otherwise dispose ofit.

The rapidly revolving lickerin creates a strong draft downwardly throughthe hop per or chute 22, hence the stripped n'mierial will be drawn intothe lickerin, and no danger exists of throwing the stripped materialover the upper end of the hopper.

To prevent the strono' draft created in the lickerin hood from alectingthe operation. a stop of suitable construction, and indifill cated at55, is attached to the hood ot the lickerin.

Having thus described the invention What is claimed as new is z- 1. lnan apparatus of the class described carding cylinder, a flat devicecooperating with the carding cylinder and operating oppositely thereto,a lickerin cylinder, and means for detaching the material picked oil bythe flat device and returning it to the lickcrin.

2. The method ct treating laps oi? fibrous material consisting insubjecting the lap material to the action of a lickerin andcardingcylinder, subjecting; the lap mate rial While on the cardingcylinder to action cl ahflat device operating reversely to the cardingcylinder, and detaching the portion picked off by the flat device and returning it to the lickerin.

3. in an apparatus of the class described a carding cylinder, a fiatdevice cooperating with the carding cylinder and operating oppositelythereto, a liclrerin cylinder having a shield device with an opening inone side, and means for detachmp; the material picked oil by the flatdevice and feedingit through the openin erin cylinder.

5. lln an apparatus of the class described a carding cylinder, a flatdevice cooperating with the carding cylinder and operating oppositelythereto, a lickerin cylinder, a comb device between the lickerincylinder and the discharge end or the flat device, and means foractuating the comb device to cause it to detach the material picked oilby the flat device and return it to the lickerin.

6. in an apparatus ot the class described a carding cylinder, a flatdevice cooperating With the carding cylinder and operating; oppositelythereto, a lickerin cylinder, a comb device between the lickerincylinder and the discharge end oi the Hat device, and. a guard deviceyieldably supported adjacent the comb and operating to hold the flatmembers in position for the action of the comb.

7. The combination With a carding cylinder and a Hat device and alickerin, of a vibrating; comb device operating; to remove thestrippings from the flat device and teed it to the lickerin.

8. The combination with a carding cylinder and a flat device and alickerin, oi a guide tunnel between the flat device and the lickerin,and a vibrating; comb device operating to remove the stripping-s fromthe flat device and feed it to the guide funnel and thence to thelickerin.
